CONDENSER SYSTEM.

SPECIFICATION forming part of Letters ratentno. 725,212, dated Apri1'14,1:903. pp i filed April 1 2- Serial No. 104.805. (N0 model.)

To'otZZ whont it nuty concern:

Be it known that 1, WILLIAM 0. BROWN, a citizen of the UnitedStates,residingin the borough of Richmond, city of New York, county ofRichmond, and State of New York, have invented certain new and usefulImprovements in Condenser Systems, fully described and represented inthe following specification and the accompanying drawings, forming apart of the same.

The object of the present invention is to provide an improved condensersystem of that class employing surface condensers, and especially toprovide a construction for efliciently separating the air and otheruncondensable vapors from the water and, delivering them from thesystem.

A further object of the invention is to provide an apparatus in whichthe water of condensation is efficiently removed from the surfacecondenser whatever be the variation in amount of water flowing from thecondenser.

The following are the two broader features of the invention: thecombination,with a surface condenser and air-pump, of an air-coolerarranged so that the air passes through the cooler on its way to theair-pump, and the air is thus cooled and any condensable vapors thereincondensed, the cooler being preferably inserted with thecirculating-head of the condenser, so as to be cooled by the circulatingwater, and the combination, with a surface condenser, of a centrifugalor turbine pump for removing the water of condensation, so that thedelivery of the pump will vary with the amount of water passing from thecondenser and even a very small flow from the condenser be taken care ofby a pump running at a constant speed without any floatvalve or otherspecial control or regulating apparatus.

The invention includes also various features of construction andcombinations of parts in condenser systems, all as more fully describedhereinafter and particularly pointed out in the claims.

In the accompanying drawings, in which all the features of the inventionare shown as applied in a simple preferred form, Figure 1 is a sideelevation of the condenser system. Fig. 2 is an end elevation of thesame. Fig. 3 is a water of condensation.

Referring now particularly to the construction shown in Figs. 1 to 5, Ais the condenser, which is shown as a horizontal condenser, having theinlet B at the top for the exhauststeam and the usual vertical tail-pipe0, opening from the bottom of the condenser for the The condenser hasthe tubes D for the circulating or condensing water, which tubes open atopposite ends into the inlet-chamber E and outlet-chamber. F for thecirculating or condensing water, with which, respectively, connect theinlet and out- The inlet-pipe E for the circulating water connects withthe pump G, by

which the condensing water is forced through" the condenser, this pumpbeing shown as a centrifugal or turbine pump operated by the motor H.The tail-pipe O, through which the water of condensation passes from thecondenser, is shown as extending downward into the pit below thecondenser, as usual in this class of apparatus, and is connected by pipe0' to the centrifugal or turbine pump I,which is shown as actuated bythe long shaft 10 from the motor K, placed on the same level as themotor H. that the means by which the pump I is actuated and itsconnections with the condenser are not important so long as the water ofcondensation is delivered by a centrifugal or turbine arranged so as tosecure the results of the invention.

Referring now to the devices for removing the air from the condenser andcooling it, the air is collected from the condenser by a pipe L in thelower part of the condenser, provided with small openings 11,throughwhich the air enters, this pipe being shown in the form of across extending well over the bottom of the condenser, and the pipe L isconnected by pipe M to the chamber N at the end of the condenser fromwhich the air passes to the air cooler. This aircooler may consist oftubes running through the condenser-head from one side to the other; butpreferably 1 It will be understood, however,

-to the hot-well or elsewhere.

use the construction shown, in which inner and outer pipes 12 13 in thecirculating-water chamber E are arranged so that the air passes fromchamberN through the tubes 12 and then returns through tubes 18 intochamber O at the same side of the condenser as chamber N, with whichchamber 0 connects the air-pipe P, forming the suction-pipe of theair-pump Q, which is shown as a common crank-driven plunger-pump. Thechamber 0 and pipes 12 13 form not only an air-cooler and supplementarycondenser, but also a separator for separating any condensed liquid fromthe air, any such liquid passing into the bottom of chamber 0 andthrough pipe 25 If desired, of course, a liquid-separator distinct fromthe cooler may be put on; but the construction shown is efficient.

The construction shown in Fig. 6 is or may be substantially the same asthat above described, except that the pipe L for collecting the air fromthe bottom of the condenser is provided with openings 14 on its upperside, and this pipe is covered by a hood 15, which prevents the waterpassing into the pipe from above as it condenses in the upper part ofthe condenser. The form of the bottom of the condenser is such that thecondensing Water flows from the condenser into the tail-pipe withoutpermitting the collection of water in the condenser to a depth above thepipe 14, so that the air-pipe is kept clear from condensed water, exceptas water-vapor may pass through the air-pipe with the air.

The cooling of the air and the condensation of any condensable vaporstherein on their way from the condenser to the air-pump secure a muchmore efficient action of the condenser system and of the air-pump. Theremoval of the water of condensation by the centrifugal pump or turbinesecures the efficient delivery of varying amounts of water by a pump runat a constant speed and retains even the smallest amount of water, so asto keep the condenser clear, and this is impor tant also in securing anefficient and economical operation of the system.

While the air-cooler is preferably placed Within the condenser orcondenser-head, so as to be cooled by the incoming condensing water, itwill be understood that the air-cooler may be otherwise arranged andcooled and that the invention is not to be limited to the special formof apparatus shown as embodying the invention, as this may be variedwidely While retaining the features claimed.
